Do you want to buy a horizontal circular sawmill in Moscow?

Disc sawmill

A circular sawmill is a machine for processing wood for vertical or angular sawing, an excellent alternative to a band sawmill.

The corner circular sawmill allows cutting in two directions at once: across the log and along the log. Wood with a diameter of 70 mm or more is processed using circular saws on angle-saw circular sawmills. The corner sawmill does not require installation on a special platform. The only condition for the uninterrupted operation of a circular sawmill for miter sawing is the absence of exposure to precipitation on the device.

Horizontal circular sawmills are no less common in the woodworking industry. Such sawmills are disassembled and easily transported. The main advantage of horizontal circular sawmills is the absence of idle running. People who do not have special skills can work on a horizontal circular sawmill. Control is carried out using the control panel.

vertical

disc sawmill is necessary for the production of timber and boards. Using a vertical circular sawmill, you can get ready-made lumber in one pass.

A circular sawmill with an edge-trimming
unit
is a mechanism that is attached to the main carriage of a circular sawmill to produce edged lumber in one processing.

A double-disc sawmill is a high-performance machine that allows you to process lumber with two circular saws.

Woodworking machine capabilities

Disc sawmill is a woodworking machine used for longitudinal cutting. The purpose and parameters of the equipment make it possible to change the shape of the logs. But the features of this saw will not allow finishing on the surface - only dividing the original workpiece into various parts.

Those who are seriously starting or planning to start their own log processing business should buy a machine. As statistics show, at the present time this work is in great demand.

Options

It is necessary to pay special attention specifically to the technical parameters of the equipment, since the potential for using this set for wood processing depends on them. A few details to remember:

1. The length of the supplied blanks depends on the size of the particular machine; we must remember that you should never hold the main part of the log suspended without additional support, because it will not be fed correctly.
2. The landing diameter of the disk is usually the same, but there is a chance of deviations.
3. The sawmill has restrictions on the diameter of the tree.
4. How many revolutions does the electric motor make? In more modern models, you can change the number of revolutions.

Sawmill control

Some models do not require a solid foundation and can be installed both outdoors and in a building. The entire work process is done manually. There are no obstacles for the machine in the form of different climatic conditions. The principle of operation is as follows: 2 rotating disks must lower to the required amount and move along the tree, as if cutting out lumber of the desired shape. The carriage is moved by an electric drive, and manual adjustment is also possible. The saw blade set includes a circular sawmill, but it is additionally possible to purchase an electromechanical feed and an electronic ruler. To understand how to properly saw on a sawmill, below is a video of working on a sawmill.

Shape and number of teeth

Rip sawing uses circular saws, which do not have a very large number of teeth. This can be explained by the huge load of saw teeth, plus small depressions are needed to sift out sawdust.

When a saw has many teeth, then with the same engine energy, it will work faster than a second one with fewer teeth, but the tooth is stronger in the second case, which means that it will take less time to reach the point of the blade.

Help with sharpening

In order to sharpen the disc correctly, it is better to buy a sharpening machine, since unauthorized use will damage the equipment, the device will behave incorrectly, and this will undoubtedly lead to a decrease in work efficiency.

Which circular sawmill to choose?

There will be no answer to this question here, since everyone must choose for themselves, but here are a few models that deserve attention:

“PDU two thousand Buran” is an angle saw that runs exclusively on gasoline with a maximum power of 25 kW. It is needed for sawing wood into several types of materials - timber, boards, etc.

The features of the circular sawmill are as follows:

• Thanks to the gasoline engine, you can work in places where there is no electricity.
• Small expenses.
• It is easy to achieve excellent geometry due to the fact that the tree does not bend at all.
• The device is easy to repair for the average person, since the components and parts themselves are simple.
• Bearings, belts and other parts made in Russia are used.
• The cut is made in both directions.

Sawmill "PDPU 600" characteristics:

• the diameter of the processed log can reach up to 800 mm;
• machine length is 1800 mm;
• width 1700 mm;
• height 1750;
• the assembled machine weighs 1100 kg;
• engine power 15 kW.

Introduction

This question is very serious, since, for example, the same ribbon costs 200 thousand rubles, but for example, an angle saw with the same productivity will cost 1.5 - 1.7 million rubles.
That’s why I raise this issue, since many novice businessmen, newcomers who have not yet fully understood the sawing technology, begin to “get into deep matters” and in the end do not always get the desired result. The issue of purchasing an angle saw is faced at the following stages:

• Creation of production from scratch, choice of sawing technology;
• Increase in production capacity;
• Shortage of radial lumber;
• Processing of thick wood.

So the main problem is that beginners overestimate information from the Internet and still, before purchasing such expensive equipment, they need very important arguments.

Purpose

A circular sawmill is equipment necessary for longitudinal cutting of logs and other lumber. The purpose and characteristics of this device allow changes in the geometric shape of lumber. However, the quality of such a sawmill will not allow for surface processing work - only dividing the initial workpiece into separate parts.

The device should be purchased primarily by those who plan to start their own wood processing business. As reviews show, this type of service is in great demand today. Quite expensive equipment, as well as its maintenance, will quickly pay for itself under conditions of intensive use.

Circular saw: where to buy and how to choose?

Today, every self-respecting master has a circular saw in his arsenal. After all, without a doubt, a circular saw is an indispensable tool for repair and construction work. However, if you have not yet managed to purchase this item, then the tips presented below on how to choose a circular saw will help you with the right purchase.

How to choose circular saws? How to choose circular saws?

The circular saw is designed for longitudinal and cross cutting of various materials. For example, for sawing wood, plastic, metal, drywall and other materials. How to choose a circular saw? First, you need to decide for what purpose and how often you will use it. Circular saws can be divided into household and professional. Household saws are not intended for constant use, so if you need a saw in your professional activities, you will have to choose a more expensive option - a professional circular saw. Next, you need to decide on the diameter of the saw blade; the depth of the cut will depend on it. Saws with a cutting depth of 50-65 millimeters are often found. Such saws are quite maneuverable, and the cutting depth is sufficient for various jobs. For professional circular saws, the cutting depth can be 100 millimeters or more

But such a circular saw will weigh more than 10 kilograms, therefore, you should pay attention to whether it is possible to install it permanently. Circular saws can be: 1. Low-power - up to 800 W

2. Average power - from 800 to 1200 W. 3. High power - more than 1200 W. The saw base can be cast or stamped. For professional work, it is better to choose a cast platform, as it is less susceptible to deformation. An important factor when working with a tool such as a circular saw is safety. Therefore, many manufacturers make a protection button next to the power button against accidental activation. This means that in order for the saw to start working, you must first press the protection button. Also, some tools are equipped with a safety clutch, which stops the disc if jamming occurs. Some circular saws are equipped with a laser pointer, which helps make more precise cuts.

Design selection

The design of a circular sawmill is being developed for specific needs. Productivity, log width, even cut along the entire length of the workpiece require certain technical solutions in the assembled equipment. When feeding manually, the plane wave of the resulting board increases. The size of the saw blade and the limits of its displacement relative to the stop pad will determine the maximum size of the wood for sawing.

Main nodes

The components of the future machine must first be correctly positioned on the drawing. The device of any homemade disk sawmill includes:

• frame. Unites all components into a functional whole. At the same time, the distance between parts must allow for safe DIY work, maintenance, cooling, and waste disposal. The main qualities are stability, rigidity;
• engine. The electric three-phase version is selected according to power and number of revolutions. Operating voltage 380 V. If there is no connection to the network, install a gasoline engine with a step-up gearbox;
• cutting unit. Placed horizontally, vertically. Consists of one disk or two (corner). A single saw can be fixed in one specified position or rotated 90° to eliminate reverse idling (cutting an angle);
• supply line. A simple homemade product is limited to a fixed table with manual feed. This type is used for small DIY work with small workpieces. A massive log is fed under the knife on a carriage;
• Remote Control. Performs on/off operations, available control switches (revolutions, feed, indication). It is carried out to a place on the frame that is convenient for work and control of the process.

Two disks

The design of a circular sawmill with two simultaneously operating cutting tools allows the processing productivity to be increased. They are located at right angles to each other. Such homemade devices are more difficult to manufacture.

Each disk is equipped with its own motor and drive. The rotation frequency is selected to be the same.

Types of cuts

The horizontal movement of the angular pairs of the disk with the drive mechanism occurs on a movable carriage. Guides are placed under it. To adjust the relative position of circular saws with your own hands, each pair is equipped with adjustment devices.

Conclusions and recommendations

Thus, when planning to purchase a sawmill for work, it is necessary to take into account a number of factors, such as the nature of the lumber that will primarily be dealt with, the qualifications of the operating personnel (including experience with various saws), the internal conditions of the enterprise and the associated priorities.

You should also remember:

• the quality of edged lumber produced on a corner sawmill is higher than that of strip and frame equipment;
• the cost of saw blades for corner sawmills is quite high, but its maintenance costs are lower and its service life is higher than that of tools for band sawmills;
• for the most efficient sawing and achieving high productivity on angle saws, it is necessary that the power of the motors on the saw spindles be at least 22 kW;
• To increase the productivity of the sawmill, mandatory mechanization of loading and unloading operations on the machine will be required, as well as automation of all processes.

Where there is no electricity

“PD-2000 Buran” is a circular rotary sawmill equipped with a PM3-640-34 gasoline engine with a power of 34 hp. With. (25.35 kW). It is intended for sawing round logs and blanks into all types of lumber - timber, beams, edged and unedged boards, etc.). Edged lumber can be obtained by turning the saw 90 degrees.

Among the advantages and features of this gas-powered circular sawmill are the following:

1. Low operating costs.
2. There are no drive components that significantly depend on the ambient temperature.
3. Cutting can be done in both directions thanks to a circular saw with a diameter of 560 mm.
4. The gasoline engine allows you to work in areas with poor electrification or directly on the plot.
5. When sawing, the log does not bend; the parameters of the sawmill make it possible to obtain lumber with ideal geometry.
6. Due to the reliability of the cutting element, the unit allows you to work with difficult-to-cut materials - with high density, resinous and rich knots. As wear occurs, the disc is replaced.
7. Easy transportation and quick installation are a consequence of the comparative compactness and simplicity of the operating principles.
8. Russian-made drive elements are used: bearings, motors, belts and other available parts.
9. Ease of repair - there are no complex components and parts, frame elements are made of affordable, standard rolled metal.

Characteristics of the rotating disc sawmill "Buran":

• diameter of sawn log: 800 mm;
• processed log length: 6500 mm;
• circular saw diameter (external and internal): 560/50 mm;
• productivity on unedged boards 50 mm: 10-12 shifts/m3;
• maximum cutting depth: 200 mm.

Types of sawmills

The modern market for woodworking machinery offers the following types of sawmills:

• tire;
• tape;
• disk.

Disc sawmills come first in popularity on this list. The reason for this is ease of operation, high performance and long service life. In addition, their cost cannot be called high. However, band and tire sawmills are just as good units as disk sawmills, only their productivity is slightly lower. The design of these sawmills is more complex, which is the reason for their higher cost.

Making a homemade sawmill

Before manufacturing the installation, detailed drawings of all components included in the design of the unit should be drawn. The simplest installation option is a single-disc sawmill. The scheme of such a design includes the following elements:

• moving carriage;
• two electric drives.

One of the electric drives ensures the movement of the portal along the guides, and the second drive serves to move the circular saw.

Sawmill assembly diagram.

This design is called horizontal. The device carriage is made of metal; it should easily move on rollers along the installation guides.

Making equipment with your own hands begins with preparing tools and materials for construction, these are:

• construction trestles;
• boards;
• metal plates;
• elements;
• electric motors;
• a set of tools and accessories for assembling the unit.

To manufacture the unit, you first need to assemble the frame of the device. For this purpose, construction trestles are combined using boards. The length of the boards used depends on the size of the material that is supposed to be processed on a homemade machine.

After making the frame, proceed to the plane of the table. Its base is made of wood, and metal plates with a width of 230-250 mm and a thickness of 1.2 mm are fixed to the surface. The plates are connected to each other by jumpers and screws. After making the table, a groove is made in its wooden part in such a way that the installed circular saw does not come into contact with its edges.

You can make a cutting tool yourself, but it is best to purchase it at a hardware store. The disk is fixed on a shaft, the drive of which is carried out using a belt drive. When securing the engine, it should be possible to move it slightly, which is necessary to tension the belt drive. The guide for the sawmill is made of boards.

Advantages

1. The size ruler is equipped with tips for the operator. This will allow you to quickly and accurately set the desired size without lengthy calculations.
2. Ideal geometry of the resulting lumber.
3. Minimal adhesion of sawdust to the guides.
4. The lowering and raising of the saw frame is carried out by an electromechanical drive. For more precise adjustment of the required size, the electric drive is equipped with a pulley with manual adjustment.
5. Improved rail track and guides made of calibrated rolled steel.
6. Easy to maintain and operate.
7. There is a certificate of the Eurasian Union.

If desired, the sawmill can be supplemented with the options “smooth feed”, “electronic ruler”, etc.
